Got my Maestro and/or SmartSDR and 6600 working with my RF-Kits B26 RF-2K+ amp in time for WPX

This was my first chance to really use my new rig.  The receiver and transmitter are very impressive!  The slice receivers, the AGC-T, and DSP filters are very impressive. So is the transmit EQ and other audio controls.  Using my new radio was a lot of fun.  After the contest I had good success testing the Maestro on Wifi (LAN).  Things are looking up!
And something very interesting happened during the contest (besides so many good signal and audio reports). Another ham let me know of a propagation change.  It happened like this.

After a lull in stations calling me, I heard an LU6 station calling.  I replied with my exchange information but he kept repeating his call. I repeating my exchange...  That's when another station (anonymous)  let me know my Run freq was also occupied by DX .  The letters DX appeared in my waterfall.  Where can I acquire the Text-to-Sound software to do that?
